De Sigma Delta HP-10 draadantenne biedt veelzijdigheid en hoge prestaties door configuratie als Delta-loop of Quad-loop. Afhankelijk van de opstelling is de antenne ideaal voor zowel korte-afstandscommunicatie als DX-verbindingen. Als Delta-lus bereikt de antenne een versterking van circa 3,2 dBd in de voorkeursstralingsrichting.
Kenmerken van de Sigma Delta HP-10:
- Veelzijdige configuratie: Kan worden ingesteld als Delta-lus of Quad-lus, afhankelijk van uw voorkeur en opstellingsmogelijkheden. Delta-lus biedt een versterking van 3,2 dBd, terwijl de Quad-lus een versterking van 2,8 dBd bereikt.
- 4:1 Balun: De antenne wordt geleverd met een 4:1 balun en drie isolatoren voor horizontale Delta-lus montage. Voor ervaren gebruikers kan de antenne met enkele aanpassingen worden ingesteld als een Fullwave Quad-lus.
- Monobandantenne: De kleinere Sigma Delta HP-loops zijn ontworpen als monobandantennes en kunnen zonder optionele antennetuner op de betreffende band over het gehele amateurradiofrequentiebereik worden gebruikt. Met een optionele antennetuner zijn ook andere banden mogelijk.
- Aansluitingen: De balun heeft een PL-bus voor het aansluiten van een 50 ohm coaxkabel (bijv. RG-58, RG-213, H100, enz.).
OPMERKING: Versie 2 - 11 juli 2024 Het vermogensvermogen is alleen bedoeld voor intermitterend amateurradio gebruik (400W CW of 500W SSB) en niet voor AM-uitzendingen of digitale datamodi (FT-x, RTTY, enz.), of constante draaggolf datamodi. Voor AM-uitzendingen is een veel krachtigere balun vereist.

Perfect For Sophia!
Size: 1.8in for Puppy Dogs, Size: 1.8in for Puppy Dogs
These little balls are the perfect size for Sophia who is a 7 lb Yorkie with a teeny tiny mouth. The slots in the balls make them very easy for her little teeth to grab hold of and carry. The quality of the rubber is excellent, strong and durable. They're holding up great so far! She loves them and so does her Mama! 5 stars!

Horrible, don't buy
Size: 1.8in for Puppy Dogs
I wanted to love these. They had so much potential. It's a good size. It seems like a good shape. But ...
1) first red flag should have been the packaging. It looked like it was a dollar store item that had beenblost on the shelves for years.
2) the rubber is super flexible. I was expecting it to be sturdier. I can flatten the ball without lich force. Maybe that doesn't matter. Naybe flexible is good. But I never got a chance to test out it's durability against a pup because...
3) it smelled. I expected it to smell like rubber, like most rubber toys. Rubber smell is okay. Usually rubber smell goes away. But, this was NOT a rubber smell.
It smells like peppermint or something similar. It's like someone sprayed essential oils when mixing the rubber and now the smell will not leave.
I soaked it in dawn soap half the day and overnight. I rubbed. I scrubbed. The smell actually gets worst the more you scrub it!!! It's like a scented marker or scented eraser, but you do NOT want the scent in a dog toy!
My dog cannot smell the food in it because the smell of the weird mint-like scent is so overpowering. He saw it had food, and wanted it, but every time he started sniffing wildly, he would recoil.
Whoever thought it was a good idea to scent this was WRONG.
Mint in the form of an essential oil is extremely poisonous to dogs!! So, why they would put a mint-loke scent ijto the dog's rubber treat toy is beyond me.
I would return this if I hadn't throw out the package immediately. I considered pulling the package out of the trash once i realized the scent issue but other trash had already been dumped into the trash can over it and i didn't want to dig through trash.
The ball is still soaking in soap. I scrubbed again this morning. I let obe dry out. No luck. It actually seems to get worst the more you scrub, like it really is embedded in the rubber itself. Yuck!!!

Great enrichment
Size: 2.8in for Small & Medium Dogs
These are great for our 3 dogs, theyβre durable and strong. The pup ford training treats fit great into these and it takes our dogs a good bit to get all the treats out. Easy to clean and a great enrichment toy, will buy again!

My dog looks forward to this every day
Size: 2.8in for Small & Medium Dogs
My dog used to have separation anxiety every time I left the house. I tried to find things to distract her when I left, but nothing kept her attention long enough for me to get out of the house. I stuff treats in this ball and she keeps focused and gets all of the treats out. Perfect solution to keep her occupied as I leave for work. Very easy to put treats in and Iβve had it for about 6 months now, which is great because my dog chews toys to pieces within days! High quality ball. I love it so much (well, my dog loves it so much), I bought one to give my neighborβs dog.

Good toy, wish it was slightly bigger
Size: 2.8in for Small & Medium Dogs, Size: 2.8in for Small & Medium Dogs
I got the medium to large size ball for my elderly boxer who has suddenly taken to chewing on everything. The toy has been a decent purchase.
Pros: not incredibly stiff plastic for elderly dogs. Easy to manipulate to put treats in the spikes. Easy to clean. Seems engaging for my dog.
Cons: probably not for super chewers. This size is probably too small for large or extra large dogs. My dog can easily fit this in his mouth and I wish it was just a little bigger. The ball can only hold one mini milk bone per slot, so it makes for treats to be really easily pulled out. Can't comment on durability yet, haven't had it for long enough.
Overall, I like this toy. I just wish it was slightly wider or bigger.
